Title: Vee tipper unloading
Post by: Gerhard Novak on December 23, 2015, 14:29
Vee tipper unloading
Hi, this is the first time I start a new topic - so please apology if there are any technical hick-ups.
And actually it is not a new topic, as I have seen a thread from 05.02.2014 about exactly this topic.
It was called How to get Vee tippers to tip and was started by Chris Wright.

As I did exactly that on my combined layout (H0 - H0e) called St. Georg I would like to describe it here. Also I am starting a new lay-out, and I will use a similar feature there so we can see later even the preparation of the tipper cars in detail.

Short description: The tipper cars need to be modified, to allow a free movement of the tipping part as well as some weight - a) to keep the car in the track and b) to allow the tipper bucket to swing back into horizontal position by gravity.

To get the bucket moving I glued a small pin of 0.3mm steel wire on to the top. This is hardly visible for the average visitor, especially as the pin is approximately 3mm long.

On the structure where the unloading happens - a lever - made of the same 0.3mm wire - moves the bucket to vertical position and unloads. The lever is approximately 12mm long - this allows finding the right unloading position without too much precision in shunting. By the way - as we speak about a small Diesel - DCC helps not to get stuck...

As I am probably too stupid to attach a picture from Flickr or Google Photo I use the workaround of using an attachment....

It might be down to the settings on the image - is it "public"?
If I click on the link it asks me to logon with my Google account, and when I do, it gives me a 404 error - "not found"
This probably means either that the image is only set to be seen by you or that the link is not correct

If I search for the image using the long string of characters, it comes back with "no results"

And now another picture - a bit bigger - where you can see clearly the pins on the first 3 tipper cars as well as the lever.

That looks pretty neat, Gerhard. What scale are you working in? How is the lever operated?

David, scale is 1:87 (H0e). Rolling stock is Roco. The H0e part was actually creared to hide a return loop of the H0 which is below. I have seen hidden return loops before, mainly with villages on top, and I thought I could do something different. So "La miniera" (the mine) was born. Why Italian? Well I lived in Italy for 11 years. My layout had a border station (St. Georg) as a main feature and La miniera was hiding the return loop on the Italian side while the othe side featured Austria (which is where I was born).

How was the lever actuated? The lever but also all 3 shutes where moved by RC servos which were situated below the baseboard. I made a small handheld device using so called servo tester circuits (very cheap...) to move the shutes and the unloading lever.
you can see my son operating the unloading system at "Trenini in mostra", 2008, Carnate, Italy. The guy is an adult in the meantime...

I will again use the attachment feature to add a picture, if one of the forum members could explain to me how to use Flickr or Google Photo I would be very happy as the attachment feature cuts off at 300kb which is not too much...

This is a very clever and interesting solution Gerhard. Thank you for sharing it with us. We look forward to hearing and seeing more of your modelling.

Happy Christmas!

Mick

Gerhard:  Thanks for the further details of your layout.

I use Flickr to post photos here:
-  upload photo to your Flickr account
-  prior to posting, select your chosen photo and open it. Click on the curved white arrow at the bottom (which allows you to share a photo), select the 'BB' option and then medium size - about 800 x 600.
-  the appropriate code will then be displayed selected (in blue), ctrl-V to copy it and then ctrl-P to insert where you want the photo to appear in your post here on the forum.

At least, that works for me, though life isn't always that easy so it may not work for you! Some people struggle with Flickr but so far I've usually managed to get it to work okay. Good luck!

Seasons greetings.

David.

Finally I got it how to work with Flickr (I think...) Took me only a week. Shame for an engineer...

But here we go - have a look at the unloading bridge in action.  click on the picture to start the video.
(I can see it - it doesn't mean everybody can see it... Please give me a feedback if you can see the video - thanks)

click on the picture above as it is a video.

My plan for the next layout is to integrate something similar. Of course not the same...
